TWIN SPRING FOR BED-BOTTOMS.

SPECIFICATION forming part of Letters Patent No. 249,305, dated October18, 1881.

Application filed August 27, 1881. (ModeL) To all whom it may concern Beit known that I, JOHN GILLILAND, a citizen of the United StatesofAmerica, residing at Payneville, in the county ofMeade and State 5 ofKentucky, have invented a certain new and useful Improvement in TwinSprings for Bed- Bottoms; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled roin the art to which it appertains to make and use thesame,reference being had to the accompanying drawing, and to letters orfigures of reference marked thereon, which form a part of thisspecification. 1 The object of my invention is to so form the connectingportion of a twin spring that the bearing-surface thereof shall becontinuous throughout the entire space between the upper terminal coilsof each spring of the pair, so 20 that a bed-bottom composed of twinsprings of the form herein shown and described shall present acontinuous supporting-surface for the mattress, and this without the useof separate connecting links or bars extending from spring 2 5 tospring. 7

My invention properly belongs to that class wherein the material formingthe springs is bent into various shapes at that portion which joins thetwo upper spirals of the springsthat is, the upper spiral of each springof the pair is continued or integrally merged into a connecting portionin various forms and for various purposes; and my said inventionconsists in the form of said connecting portion, as shown 3 anddescribed, and as hereinafter specifically set forth in the claim.

The drawing represents a plan of a twin spring embodying my invention,and A represents what I shall, for convenience in descrip- 0 tion, termthe right spring of the pair, and B the left. The upper spiral of theright spring is inwardly curved in V form, as is also the upper spiralof the left spring, which is curved oppositely to the right, and the Vofeach spiral is connected with the other by means of a di- 5agonally-disposed S-shaped bar.

Referring more particularly to the drawing. andim agininglines drawnfrom the upper spiral of one spring to that of the other on each side,as y, it will be seen that the Vs b and a each point inwardly andterminate at about a central line parallel with lines 00 and y, andreach outwardly the lines as and 1, respectively, and are connected bythe S-shaped bar a, diagonally disposed, as above stated.

The benefits accruing from this construction are not only a uniformbearing-surface, but when pressure or weight is placed wholly on one orthe other of the Vs it is more evenly distributed to other portions ofthe connection and the springs than would be the case were theconnection shaped with less re-entering curves and outside loops.

I am aware that twin springs are not new, and that their connectingportions have been extended beyond the side lines, so and y, of thespirals for the purpose of providing means for connecting rows ofsprings, and that they have been provided with one loop on one and twoloops on the other side, and I do not claim such as of my invention; but

What I do claim as new, and desire to secure by Letters Patent, is

The twin springs A 13, having their integral con nectin g-wire bentintotwo in wardl y-project- 7 5 ing Vs, b and c,joined by adiagonally-disposed S-bar, a, substantially as shown and described.

In testimony whereof I have atfixed my signature in presence of twowitnesses.

JOHN GILLILAND.
